Vidcast: Less Long CoVid With Omicron
Your chances of developing Long Covid after an Omicron infection is anywhere from 20% to 50% less than following a Delta infection. Investigators at King’s College, London studied more than 56,000 UK adults who tested CoVid positive during 11 weeks from late December 2020 to early March 2021 when 70% of UK cases were due to the original Omicron subvariants.
For Delta, 10.8% of those infected developed at least one Long CoVid symptoms compared with only 4.5% of those falling victim to Omicron. The differential risk of Long CoVid after Omicron vs. Delta was least for those who were vaccinated 3 to greater than 6 months before infection and that risk was 24 to 26%. Those vaccinated less than 3 months before infection did better and were 50% less likely to get Long CoVid after Omicron than after Delta.
The catch-22 here is that this study offers no information about the risks of Long CoVid from our latest batch of Omicron sub-variants including BA.2, BA.2.12.1, or the very latest BA.4 and BA.5. Stay tuned as the story continues to unravel.
